Patent number: 7256131Abstract: The present invention provides a method of patterning a substrate, the method including, inter alia, forming a multi-layered structure on the substrate formed from first, second and third materials. The first, second and third materials are exposed to an etch chemistry, with the first and second materials having a common etch rate along a first direction, defining a first etch rate, and the first and third materials having a similar etch rate along a second direction, transversely extending to the first direction, defining a second etch rate. Typically, the etch rate is selected to be different in furtherance of facilitating control of the dimensions of features formed during the etching process.Type: GrantFiled: July 19, 2005Date of Patent: August 14, 2007Assignee: Molecular Imprints, Inc.Inventor: Dwayne L.
